28. Distances marked on the figure below are in feet. Points B, E, F, and C are collinear as are points A, H, G, and D. If the area of rectangle ABCD is 33 square feet and EH and FG are each perpendicular to AD, what is the area, in square feet, of trapezoid AEFD?

Answer and Explanation

Your Answer is

Correct Answer is H

Explanation

Because the area of ​​the rectangle ABCD is 33, AB=3, so BC=AD=11. Therefore, EF=five. According to the trapezoidal area formula, the area of ​​AEFD=(11+5)×3÷2=24. Choose H.
